Abstract : Tests to measure draw load reduction versus draw velocity at a constant energy density were repeated for tinned copper wire. It was found that with a pure sine wave input at the resonant frequency (nominally 20 kilocycles per second) of the system, that parasitic frequencies were self-induced in the wire. The pattern and distribution of energies among the various waves were responsible for further decreases in draw load. (Author)
